Alfred Hitchcock's cameo, and the crows perched all over a climbing frame before attacking Krabappel, reference Hitchcock's film of The Birds.

Bart and Stephen King writing "All work and no play makes Jack a dull boy" is a reference to Stanley Kubrick's version of The Shining. The first segment of Treehouse of Horror V is a homage to The Shining.

Groundskeeper Willie's appearance is a reference to Hellboy, while his fight with Kroenen is a reference to the film.

The final segment references Pan's Labyrinth again: the throne room is the same, Marge and Homer resemble the King and Queen of the underworld, Lisa is dressed as protagonist Ofelia, there are small fairies flying about, and Bart resembles the Faun.

Freaks, No Geeks was supposed to take place in 1932 but when Homer tells the kids his story it's in the present time. Since this is non canon, he could have lived for 81 years after the incident but it says in the last article that he died. He must've faked his death at the time.
